OBJECTIVES:
To understand the use of transfer function models for analysis physical systems and introduce the
control system components.
To provide adequate knowledge in the time response of systems and steady state error analysis.
To accord basic knowledge in obtaining the open loop and closed–loop frequency responses of
systems.
To introduce stability analysis and design of compensators

feedback
